Tadpole: GEX, ADA & JBL soil are priced just about the same. If you do plan to use GEX, I'd suggest you get the 3kg Red packaging one, its shrimp friendly. Why, you may ask. Compare the soil granule size. Easier for the shrimps to push around. Another reason, since you're going for moss & fern set-up, Cherry shrimps are the cheapest and most efficient moss cleaners. Just remember to bring your temperature down to about 25C with a dual fan setup, good amount of water flow, some DIY co2 and light, mosses thrive in well ventilated & clean tanks.
The various websites do say that moss & fern don't need much light or co2, but do remember you're are recreating nature in an environment devoid of water movement.
With addition of co2, light & water current; your mosses will grow bushy and the colors will be more vibrant, trust me I speak from experience.
In my shrimp tank set-up, I don't feed the shrimps reason being there's enough dead particles in the water for it to feed on plus I don't want to add to the bio load of the tank. All I do is top-up water every other day and do a water change every week. Addition of Seachem's Flourish Excel ensures that my plants get the extra Carbon.
When adding chemicals into the water, its advisable to add half the dosage initially so as not to 'shock' your flora & fauna; then increase slowly until you arrive at the required dosage.
When you first introduce the mosses & ferns, also get a few bunches of
Cabomba Caroliniana (one of the fastest growing stem plants). Why you need to have plants that suck up the excess nutrients in the water therefore ensuring less likelyhood of an algae bloom.
